C

Isn't it astonishing how much time we spend talking about food? “Have you ever eaten …?” “What did you have for lunch?” and so on. And yet when you travel from one country to another, you will find that people have quite different feelings about food. People often feel that what they eat is normal (正常) and that what other people eat is strange or silly. In most parts of Asia, for example, no meal is complete without rice. In England, people eat potatoes every day. In the Middle East, bread is the main part of every meal. Eating like so many things we do, becomes a habit which is difficult to change. Americans like to drink a lot of orange juice and coffee. The English drink tea four or five times every day. Australians drink a great deal of beer, and the French drink wine every day.

The sort of meat people like to eat also differs from one country to another. Horse meat is thought to be delicious in France. In Hong Kong, some people enjoy eating snakes. New Zealanders eat sheep, but they never eat goat meat. The Japanese don't like to eat sheep meat because of its smell, but they enjoy eating raw fish (生鱼).

So it seems that although eating is a topic we can talk about for hours, there is very little common sense in what we say it. People everywhere enjoy eating what they have always eaten, and there is very little we can do to change our eating habits.

64. Which of the following is true according to the article?

A. All people have the same feeling about food.

B. In most parts of Asia, people usually have rice for meals.

C. People often consider other people to be strange or silly.

D. The topic people spend time talking about is bread and meat.

65. People in different countries   ___ .

A. drink the same sort of wine     B. have the same eating habit

C. eat different kinds of meat      D. have the same tea at different time within a day

66. The Japanese don't like to eat sheep meat    __ .

A. because they dislike its smell   B. because it is too expensive

C. because it is easy to go bad    D. because they think it will do harm to their health

67. English people drink tea four or five times a day    _  .

A. because they get thirsty easily     B. because there is plenty of tea in Britain

C. because of their drinking habit    D. because they have enough time to do so
